According to the passage, what is the main difference between the trombone and the tuba?
A
The tuba has buttons, but most trombones do not.
B
The tuba is smaller than the trombone.
C
The trombone makes a lower sound than the tuba.
D
The trombone's slide is longer than the tuba's slide.
A trombone is a type of instrument. The musician blows air into one end while vibrating his or her lips. The air and the vibration make a sound. The musician can change the sound by moving a special part of the trombone called the slide.
The slide is a long tube. When the musician pushes the slide out, the trombone makes a low-pitched sound. When the musician pulls the slide in, it makes a high-pitched sound. Each position of the slide can make a different musical note.
Like the trumpet or the tuba, the trombone is made out of a metal called brass. But the trombone is not like the trumpet and tuba in all ways. It is different because of its slide. Trumpets and tubas make different notes when musicians press different buttons on them. Most trombones have no buttons. Only the slide can change the notes that the trombone makes.
